[Explanation and interpretation of blood transfusion provisions for children with hematological diseases in the national health standard "Guideline for pediatric transfusion"].

To guide clinical blood transfusion practices for pediatric patients, the National Health Commission has issued the health standard "Guideline for pediatric transfusion" (WS/T 795-2022). Blood transfusion is one of the most commonly used supportive treatments for children with hematological diseases. This guideline provides guidance and recommendations for blood transfusions in children with aplastic anemia, thalassemia, autoimmune hemolytic anemia, glucose-6-phosphate dehydrogenase deficiency, acute leukemia, myelodysplastic syndromes, immune thrombocytopenic purpura, and thrombotic thrombocytopenic purpura.

Cryo-EM reveals cholesterol binding in the lysosomal GPCR-like protein LYCHOS.

Cholesterol plays a pivotal role in modulating the activity of mechanistic target of rapamycin complex 1 (mTOR1), thereby regulating cell growth and metabolic homeostasis. LYCHOS, a lysosome-localized G-protein-coupled receptor-like protein, emerges as a cholesterol sensor and is capable of transducing the cholesterol signal to affect the mTORC1 function. However, the precise mechanism by which LYCHOS recognizes cholesterol remains unknown.

Undoped ruthenium oxide as a stable catalyst for the acidic oxygen evolution reaction.

Reducing green hydrogen production cost is critical for its widespread application. Proton-exchange-membrane water electrolyzers are among the most promising technologies, and significant research has been focused on developing more active, durable, and cost-effective catalysts to replace expensive iridium in the anode. Ruthenium oxide is a leading alternative while its stability is inadequate.

Genome-wide and phenome-wide studies provided insights into brain glymphatic system function and its clinical associations.

We applied an MRI technique diffusion tensor imaging along the perivascular space (DTI-ALPS) for assessing glymphatic system (GS) in a genome-wide association study (GWAS) and phenome-wide association study (PheWAS) of 40,486 European individuals. Exploratory analysis revealed 17 genetic loci significantly associating with the regional DTI-ALPS index. We found 58 genes, including and , which prioritized in the DTI-ALPS index subtypes and associated with neurodegenerative diseases.

Convergent reduction of immune receptor repertoires during plant adaptation to diverse special lifestyles and habitats.

Plants deploy cell-surface pattern recognition receptors (PRRs) and intracellular nucleotide-binding site-leucine-rich repeat receptors (NLRs) to recognize pathogens. However, how plant immune receptor repertoires evolve in responding to changed pathogen burdens remains elusive. Here we reveal the convergent reduction of NLR repertoires in plants with diverse special lifestyles/habitats (SLHs) encountering low pathogen burdens.
